AMP Research 03968-11 PowerStep Replacement Idler Linkage Arm GM Truck Black Steel

The AMP Research 03968-11 is an OEM-quality replacement idler linkage arm designed specifically for the AMP Research PowerStep automatic running board system on GM trucks. This component is a critical part of the PowerStep's four-point linkage mechanism, enabling the step to deploy and retract smoothly each time a door is opened or closed.

Key Features:

• Direct OEM Replacement: Engineered to exact factory specifications for a precise, hassle-free fit in your existing PowerStep assembly
• Steel Construction: Built from durable steel for long-lasting strength and reliable performance under regular use
• Black Finish: Finished in black to match the factory appearance of the PowerStep system
• Idler Linkage Design: Functions as the idler (non-motor-driven) arm within the four-arm linkage assembly, maintaining proper step geometry during deployment and retraction
• GM Truck Application: Specifically engineered for GM truck PowerStep installations, including select Chevrolet Silverado and GMC Sierra models

Keeping all four linkage arms in good working order is essential for smooth PowerStep operation. Worn or damaged idler linkage arms can cause binding, uneven step movement, or unwanted noise. Replacing a faulty idler arm with this genuine AMP Research part restores proper function and extends the life of your PowerStep system. Regular maintenance — including cleaning pivot points and applying a dry silicone lubricant — is recommended to maximize longevity.
